W) a]! whom it may concern.-

Beit known that 1, DAVID C. \VALsH, a citizen of the United States,residing in the city of New York, borough of Manhattan. in the countyand State of New York, have invented a certain new and usefulImprovement in l/Vator-Coolers, of which the following is aspecilication.

The invention relates to that class of watercoolers in whichdrinking-water is supplied from an inverted demijohn or large bottle andflows to a cooling-chamber surrounded by ice or other cooling medium,whence it is drawn as required.

The object of the invention is to provide a simple and efficient cooler,inexpensive to manufacture, and so constructed as to allow easy accessto and removal of the interior parts for inspection, cleansing, andrepairs.

The invention consists in certain novel features and details ofconstruction by which the above objects are attained, to be hereinafterdescribed.

The accompanying drawings form a part of this specification and show apreferred form of the invention.

Figure 1 is a diametrical vertical section, partly in elevation. Fig. 2is a plan view, partly in horizontal section, of the coolingchamberalone. Fig. 3 is a top or plan view of the water-cooler on a reducedscale with certain portions removed or omitted.

Similar letters of reference indicate the same parts in all the figures.

A is the casingor ice-containing vessel,preferably ofcylindrical form,open at the top, and having double walls and bottom, the space betweenbeing filled with felt A or other preferred non-heat-conductingmaterial. Atube u in the bottom of the casing leads away the waterresulting from the liquefaction of the ice to any suitable receptacle.(Not shown.)

The open top of the casing is closed by a removable deck B and aremovable cover (1, each of semicircular form. The cover C is providedwith a lifting-ring C, by which it may be removed and replaced, asdesired, in supplying ice to the interior of the casing. The deck B,comprisingsomething more than half the circle, is held normally in placeby a bottle-support E, received in acireular opening 6 in the deck.

D is the cooling-chamber of circular form and having a diameterconsiderably in excess of its height, but less than that of the interiorof the casing A, in which it is received. The cooling-chamber ispreferably of copper or other metal lined with block-tin to preserve thepurity of the water passing through it and is supported a littledistance above the bottom of the casing by short legs D to permit theescape of water from the melting ice to the drain and is placedeccentrically in the casing. In the top of the cooling-chamber is athreaded nipple I), located in the axial line of the opening b in thedeck above, on which is screwed the lower end E of the bottle-holder Eof funnel shape, the upper portion flared to match to the aperture 7)and be partially sup ported by the deck, and also to the annularshoulder M of a large bottle or demijohn M, inverted in thebottle-holder.

The interior of the circular cooling-chamher is divided diagonally fromthe top on one side to the bottom on the other into two compartments byan inclined partition-plate D"of block-tin or metal coated therewith,and each of such compartments is again subdivided by vertical transversepartitions D and D, one above and the other below the plate D, as shown,each having an opening d" and (Z respectively. The lower portion of theplate beyond the partition D is also provided with a similar opening d",affording communication through the plate. The nipple D surrounds anopening (Z in the upper face of the cooling-chamber through which wateris received above the plate D from the bottleholder E, and d is anopening in a boss I) on one side of the cooling-chamber through whichwater is delivered from below tlieplate.

The cooling-chamber is held in place by a screw-threaded tube F,received in the boss D and forming part of a faucet F. The tube extendsthrough an opening a in the casing and when screwed home draws the bossD into close contact with the interior of the easing, the flange F onthe faucet serving as an abutment. Possible leakage of water from theinterior of the casing is guarded against by rubber gaskets G,interposed either between the flange and boss and the casing or in bothsituations. The faucet illustrated is of the push-button type. Anyapproved style may be employed.

In assembling the parts, the deck B and cover C being removed, thecooling-chamber D is inserted and the faucet F with its gaskets Ginserted through the casing and screwed to the boss D the deck B is putin place, and the bottle-holder E inserted in the hole I) and screwed tothe nipple D thus securing the deck B and cooling-chamber firmly inplace relatively to the casing. Ice is then introduced through theremaining opening in the top of the casing and packed upon and in thecrescent-shaped space around the coolingchamber and the cover Creplaced. The cooler is then ready to receive the bottle, which isinverted in the holder as usual, the Water therein escaping until thecooling-chamber is filled and the Water-level risesiin the bottleholdersufficiently to seal the mouth of the bottle and arrest further flow.More water is delivered as the level descends, due to withdrawal fromthe cooling-chamber through the faucet, as usual.

It will be noted that all the parts are easily removed,and any partfound to be leaking or otherwise faulty may be replaced by anothersimilar but perfect part without requiring the removal of the entirecooler for repairs. The

-invention is designed especially for use by customers ofpure-water-supply dealers, and by providing the delivery agents withduplicate parts many of the repairs required may be quickly made by suchagents without the inconvenience to the customer and to the dealerentailed by removing the cooler and the substitution of another whilerepairs are being made.

The inclined plate D causes the water to traverse the cooling-chambertwice and presents it in thin layers to the chilling effect of the ice.The vertical partitions D D serve with the inclined deck to subdividethe interior of the chamber, retard the flow in the severalcompartments, and also to strengthen the chamber to enable it to resistthe strain due to the Weight of the bottle, a portion of which is likelyto be transmitted to the chamber instead of being sustained entirely bythe deck B.

The surfaces in contact with the potable water are preferably of tin, asabove described. The interior of the casing may be of zinc or galvanizediron, and the exterior and other exposed portions may be ornamented asdesired.

Changes may be made in the forms and proportions of the parts. Suchportions as the drip-pan,waste-water receptacle, and supporting-stand(not shown) may be understood to be of any ordinary or approvedconstruction and arrangement.

I claim 1. In a water-cooler, a casing, a removable cooling-chambertherein, a delivery faucet on the exterior of said casing, extendingtherethrough and separa bly engaged with said chamber, a deck over aportion of the top of said casing, an aperture in said deck, and abottle-holder matching said aperture and separably engaged with saidcooling-chamber, whereby said chamber is held in position and said deckand chamber mutually aid in sustaining the weight of a bottle in saidbottleholder.

2. In a water-cooler, a casing, a removable cooling-chamber therein, adelivery-faucet on the exterior of said casing, extending therethroughand separably engaged with said chamber, a removable deck over a portionof the top of said casing, a removable cover over the remaining portionof the top, an aperture in said deck, and a bottle-holder matching saidaperture and separably engaged With said coolingchamber, whereby saiddeck, coolingchamber, and bottle-holder are held in position relativelyto said casing and to each other.

3. In a water-cooler, a casing, a removable cooling-chamber therein,partitions in said chamber serving to strengthen the latter and induce along travel of the Water therethrough, a delivery-faucet on the-exteriorof said casing, extending therethrough and separably engaged with saidchamber, a deck over a portion of the top of said casing, an aperture insaid deck, and a bottle-holder matching said aperture and separablyengaged with said coolingchamber, whereby said chamber is held inposition and said deck and chamber mutually aid in supporting the weightof a bottle in said bottle-holder.

4. In a water-cooler of the character set forth, a cooling-chamberhaving an inlet and outlet, a division-plate arranged diagonally fromthe upper portion of one side of said chamber to the lower portion ofthe opposite side, dividing the interior of said chamber into upper andlower compartments, vertical partitions extending from the upper face ofsaid division-plate to the top of said chamber and from the under faceof said division-plate to the bottom of said chamber and subdividingsaid compartments, and apertures in said plate and partitions, saidplate and partitions serving the double function of strengthening saidchamber and causing water from said inlet to flow through saidcompartments and subdivisions successively to said outlet.

5. The water-cooler described, comprising a casing open at the top, aremovable coolingchamber therein having its interior divided intocompartments and having an inlet at the top and an outlet on the side, afaucet on the exterior of said casing, extending therethrough andseparably connected to said outlet, a removable deck over a portion ofsaid open top, and a removable cover closing the remaining portion, anaperture in said deck, and a bottle-holder received in said aperture andseparably connected with said inlet and arranged to be supported by saiddeck and coolingcliamber, all combined and arranged to serve with aliquid-containing bottle, substantially as and for the purposes setforth.
